Except Lenovo, does. Thinkpad X-series can do both and the order is
configurable in the BIOS (at least on this X250 - I assume other models
can do this, too).
It really has a separate legacy BIOS, or it has the legacy compatibility
modules included in the UEFI firmware? I have worked with an Intel
motherboard which used the Intel sourced UEFI, and it could act as a
legacy BIOS, but was really booting UEFI to configure the processors, then
effectively loading a program that behaved as legacy BIOS, so to a
bootloader it appeared as a legacy BIOS but was in reality a hybrid
system.
